Asphalt and Fiberglass Shingles

Architectural or 3-Tab

Asphalt Shingles come in two standard design options: Architectural (also known as Dimensional) Shingles and 3-Tab Shingles. 3-Tab are essentially flat simple shingles with a uniform shape and size. They use less material and are thinner than Architectural Shingles, and are therefore lighter and lower cost for both the material and the installation. They also do not last as long or offer Manufacturer's Warranties as long as good architectural asphalt shingles. 3-Tab are still the most commonly installed in lower-value homes, such as those used as rental properties. However, they are declining in popularity in favor of the architectural style. Dimensional or architectural shingles are thicker and stronger, vary in shape and size, and offer more aesthetic appeal; casting more distinct, random shadow lines better mimics the appearance of traditional roofing materials such as cedar shingles. The result is a more natural, traditional look. While more expensive to install, they come with longer manufacturer's warranties, sometimes up to 50 Years - typically prorated, as virtually all asphalt shingle roofs are replaced before such an expiration could be reached. While 3-tab shingles typically need to be replaced after 15–18 years, Dimensional typically lasts 24–30 years. Proper roof ventilation has been known to extend the lifespan of a roof, and a strong slope that can help to prevent water damage from freezes or pooling is also helpful.
